Field-Emitter Displays for Virtual-Reality Headsets

This proposal addresses a cost-effective solution for virtual reality headsets that do not significantly sacrifice color or resolution. This new headset display could be built to be compatible with almost any desktop computer system or video format. In this program we will test the novel concept of combining color sequential filters with white light field emitter array (FEA) displays using an experimental 512X512 pixel headset size FEA display as a demonstration vehicle. This is desired in order to provide color video output at the same resolution as the monochrome display at low potential manufacturing cost derived from a reduction in electronics and connector complexity. Field emitter displays possess the potential to provide high resolution, high brightness, full color, wide viewing angle high energy efficiency, low manufacturing cost, low driver cost, thinness, and possess small overall volume. Our FEA displays permit these novel display devices to be designed to operate at high anode potentials, approaching that of CRTs, allowing the use of high efficiency RGB optimized phosphors which are commonly available.
